COMBUSTION DEVICE.

Application filed January 27, 1917, Serial No. 145,031. Renewed May 12, 1920; Serial No. 380,887.

To all whom it may concern:

Be it known that I, SAMUEL YOUNG, a citizen of the Republic of Peru, and a resident of Yquitos, Peru, have invented a certain new and usefullmprovement in Combustion Devices, of which the following is a specification.

My invention is an improvement in combustion devices, and has for its object to provide-mechanism of the character specified,

Fig. 4; is a section on the line 414: of

Fig. 3;

Fig. 5 is a vertical section through the filled container;

Fig. 6 is a similar section at right angles to Fig. 5;

Fig. 7 is a perspective view of the removing tool, and

Fig. 8 is a similar view of the inserting tool.

In the present embodiment of the invention, a furnace, which is of ordinary construction, is provided, having a combustion chamber in which may be arranged a boiler 2. The boiler is encircled by a spirally arranged draft pipe 8 opening at the under side of the boiler at each end thereof and from the middle of the draft pipe the stack 4 extends. On the bottom or floor of the chamber is arranged a casing, the said casing consisting of a base or top 5, side flanges 6, and an end flange 7, the side and end flanges having outwardly extending ribs 8 which rest upon the base or floor and are secured thereto as shown.

A door 9 is provided at the front of the furnace, and at the open end of the casing 5, 6, 7, to permit the insertion and removal of the heating units to be later described.

Each of said units is in the form of a cylindrical container 10, of metal of suitable weight, the said container having at the center of the bottom thereof an opening 11, and a lateral opening 12 in the side wall and at the bottom. A cover 13 is provided for the unit, the cover having also a central opening 14 of larger diameter than the opening 11 and coaxial therewith. These containers, which may be of any required dimensions, are adapted to be filled with fuel indicated at 15, for instance straw orhay, shavings, or

slack.

In packing the combustible material in the containers, it is necessary to provide for draft, and for this reason an opening is retained between the openings 11 and 12 and connecting said openings. 'To maintain this opening a pipe 16 is inserted at the center of the container, the said pipe being of a length to extend from the opening 11 to the opening 14, and the lower end of the pipe is supported in a recess 17 in the top of a bar 18 of wood or the like, which is inserted through the lateral opening 12 until the recess or depression 17 is at the center of the container.

The tube or pipe 16 may now be placed in the depression and will be held at the center of the container. The combustible material is tightly packed within the container around the tube and over the bar, after which the cover is placed, and the said cover may be held in place in any suitable manner, as desired or found necessary.

The pipe 16 is now withdrawn as is also the bar 18, and the unit is ready for insertion in the furnace. It will be noted that the top of the casing-567 is provided with openings 19 at intervals, and these openings are adapted to register with the openings 11 of the several units. When the units are placed over the openings in the casing, with the openings 11 in register with the openings 19, it will be evident that a draft of air may pass upward, through each container to aid combustion.

The combustibles in the containers are ignited from below through the lateral opening 12, and through the opening left by the removal of the bar. The combustible material is slowly consumed, leaving a minimum of ash and yielding a maximum of heat. The products of combustion, leaving the units, enter the spiral pipe 3, thus giving up additional heat to the boiler, eventually leaving the furnace by the stack 1.

As each unit is burned out it may be removed by the hook 20, shown in Fig. 7,

this hook comprising a rod having at one end a handle and at the other a hook, and the said hook may be engaged'with the opening 12 of the container as shown in Fig. 4c, or a ring 21 may be provided on the container for engagement by the hook. To insert a new unit, the device shown in Fig. 8 may be utilized. This said device comprises a rod 22 having at one end a handle and having at the other end a curved cross head 23 which engages the side wall of the unit to push the same into the furnace along the top of the casing.

As is well known not more than fifty per cent. of the heat produced by combustion is available. The remainder is lost through the stack and by radiation and from defects of combustion, whether said combustion is slow or rapid. With my improved system, I am able to obtain and make serviceable ten to twenty per cent. more of the heat produced by combustion, by providing for continuous and total combustion of the combustibles.

It will be understood that it is necessary to open the door 9 more or less for the entrance of air. A chimney not shown is also provided for the passage of smoke, with a damper in the chimney.

I claim In a furnace, an air supply casing formed as an inverted trough-like member closed at one end and open at the other end, the sides and closed end of said member being provided with flanges secured upon the b0ttom of the furnace, the open end of said member communicating with the atmosphere through an opening in the front of the furnace, the top of said casing having formed therein a plurality of spaced holes of relatively small diameter, and a plurality of fuel containers disposed upon the top of said casing and each provided in its bottom with a central hole registering with a hole in the top of the casing and each having a top provided with a central hole.

SAMUEL YOUNG.
